More than 99.9% of Iowa's original tallgrass prairie ecosystem has been lost. That makes our state one of the most changed landscapes on Earth. Fortunately we have the Neal Smith National Wildlife Refuge, the largest reconstruction of tallgrass prairie in the United States and Iowa's youngest National Wildlife Refuge. Neal Smith NWR offers hiking trails, an auto tour, views of bison and elk herds and the Prairie Learning Center. Listen to the files below to learn more!

Quotes from the Neal Smith Refuge
What happened? Iowa happened. We turned these rich and deep prairie soils into one of the most productive agricultural systems the world has ever known." -Jim Pease "Beneath the loess is a pre-Wisconsinan deposit of till, classically called Kansan but now called the Wolf Creek Formation in this area."
-Tom Fenton |
